Thisl invention relates to gas heaters ai1d` more partitailarly to a portable type of heateradapted tor use with `efas or fluid fuel, .sueh as oil or the like. and the object ot'my invention is to provide a heater which is not only simple in ronetruetion, but one in which the elements forming the complete unitary device are assembled and arranged in such a manner as to utilize the maximum ealoritit: value of the fuel.

lt; has 't'or a further object to provide a eombustiou ehaniber of novel construction, whereby the heat and tlame `from the burner are directed into contact witb the snrfaee ot tbe combustion chamber and heat the same to a state ot' ineandeseence, so that the outside air surrounding the eliamber and in contact therewith is'thoroughly heated and uniformly distributed. i

For the purpose ot' illustrating my invention. l have shown in the aeeompanying d rawingzs one :form thereof whieh is at present preferred by me, sinee the same has` been found in practice to give .satisfactory and reliable results, although it is to be understood that the variousy instrumeutalilies ot' w'hirh my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of thesey instrumeutalities as herein shown and described.

l"i e;ure 1 represents a vertical central seetiou of a heater embodviinlr m Y invention.

u l s h u F1g. 2 represents a section on line iena,

Fig. l. x

Similar numerals of reference #indicate corresponding figures in the drawings.

Referring to the drawings, l designates a suitable base. for a heater embodyinglr my invention, .supported upon which is an outer perforated easing Q, cariving a suitable top 3, the. said parts being secured together by rods 4 or other well known means, as will be apparenti.

5 designates a flange preferably toi-med integral with the base 1 and of annular con struction, the function ot the. same being to support the bottom plate G of the heater,

the said plate preferably being perforated to permit. air to pass to .the interior of the easingr E2 and circulate therethrough. This plate tl is apertured to receive the burner proper, the latter, in tbe present. instance,

eonsistinnr of a tubular casting 7 having a pluralitv of discharge nozzles tl angularly disposed. in order to project tbel flame lon gitudinallyot the casing i2. This castingr is preferably secured by means ot a bolt El' or 65 like. fastening' device t'o a lmnsen mixing tube 1.0 which. as here shown, is'in the `torm ot' au elbow fittiingr having' a tlanee il betweetrwbich and the casting 7 is located a packingr 'l2 to prevent leakage at the joint l70 formed' therebetween. The intake lI-l of the tube l() is provided with a plurality of openfings 14 and has a cap Al5 inovably secured thereto and provided with openingsv 16,

adapted to aline withthe openings 14 1n 76 certain positions to admitI the proper quantitl' ot' air to form n coulbustible mixture.

1T designates a supply pipe coupling suitably secured to the eap 15 and having :1

valve 1HI therein t'or the usual purpose of 80 regkulat'ingr or cuttingr ott' the supply of fuel to the burner. 19 designates a lug preferably 'formed integral with the mixture tube ltliand forming.r a means whereby the said tube may be sup orted by the base l. In

eonneetion with t te securingr of the tube l0, the plate t and the burner 7, to the base 1, it will be noted that. I `terably provide a plurality ot' stove bolts 'QOwhich pass through the :several parts and firmly unite the same with the plate (S between the burner T and the base ring or flange J'This construction is particularly advantageous sinee it readily permits the .several p rts being` disassembled and any one part b ing easily replaced should such part beeome'.-broken 0r otherwise impaired.

'2l designates an inner perforated easing here `shown as sectional and forming a eombustion enaniber, thtl material of which the saule is composed beingr preferably of metal, sheet or east. whereby when it is subjected to the heat of the products otl combustion it will become ineandeseeut thereby etl'eeting a more complete combustion and also exposl ing a large Surface to the air to be heated. ln ernuertiou with this lutter feature, it. will be noted that the asing 21 is provided with a plurality ol eorrugations 22. each of which. in the present instance. partially eni eircles onev :of the lilloise discharge nozzles nml suhstantiall contines the heat from that particular nozz egto. a distinct. zone. Fur thermore, attention is directed to vthe shape ofthis. inner casing 21 .as to its vertical .eeetxon since, inthe present instance, the sides of the casing 2l converge from the hase and form substantially :t truncated cone with.

side eormgations.

23 designates a top plate suitably secured to the inner casing 21Awhich serves, not onlg,r the purpose offen zulditional'henting surface, but also 'es o, dellector or baille to retain the products of combustion n suitable length of time withinthe casing 21, und also to Adeflect the. said products outwardly .through the perfor-ations 24; of theinner casing. This inner casing 21 is preferably rovided with siiitalllelugs 25 positioned at intervals about the hnethereo' -ttn-odapted Mening to receive store hol'ts- 26 orlile devices, for securing the Casing to .the otton .f

plate 6.

En view of the fact that provision is mode' for qomeo the cold nir entering the heater to pass exerior of the inner casing 21, l preferably provide, at n suitable point, above the said inner casing, a defleetor 2? for the pur ose of reterding and holding the mixed pro nets and air Within the heatera sulcient length off ltinie to promote, as.

nearly as possible, complete combustion but not to allow them to remain suc'iontly long 'to conse carbon monoxid to be fornied. It

Loeoooe will of course be understood that the top 3 is provided with suitable apertures 28 to allow the nir und products to pass exte-A rior ol the casing nml create within the same :i sullicient cireulationto promote combus tion.
